Synthesis and Biological Activities of Organotin Schiff Base Complexes
ISBN: 9783659560644 / Angielski / Miękka / 2014 / 84 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. 2-Thiophenecarboxylic acid hydrazide has been treated with benzaldehyde in 1:1 molar ratio at room temperature in the presence of a suitable solvent to yield Schiff base. Then it has been treated with R2SnCl2/R3SnCl in 1:1 molar ratio to synthesize organotin(IV) complexes under reflux conditions. Organotin(IV) complexes have been characterized by FT-IR and semi-empirical study. FT-IR data explains the tetrahedral arrangement of sulphur donor ligand with tin metal which is further confirmed by semi-empirical study. Least value of dipole moment of complex 3 explain the trans orientation of...

Production and Characterization of Xylanse from Aspergillus Niger
ISBN: 9783659596797 / Angielski / Miękka / 2014 / 196 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Xylanase enzymes are group of enzymes that can degrade Xylan present in plants. Xylan lignin and cellulose formed a complex matrix in plants. Lignin imparts colour to cellulose and thus eventually imparts colour to paper and pulp. Xylanase facilitates the removal of lignin from the paper pulp thus improves the brightness of paper. Xylanase was produced by Aspergillus niger using different carbon sources. UV irradiation of Aspergillus niger slightly improves the Xylanase activity than native Aspergillus niger. Twenty minutes exposure of Aspergillus niger to UV irradiation was considered...

Synthesis and Biological Activities of Sn and Pd Complexes
ISBN: 9783659607028 / Angielski / Miękka / 2014 / 80 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Tin(IV) and Pd(II) complexes are useful as antibacterial, antiviral, antifungal and antilarvicidal agents. Tin(IV) and Pd(II) complexes are also important as catalyst, water repellent, antifouling agents in paint industry and as fire retardants. Present work focus on the synthesis of tin and palladium complexes, their characterization and biological activity with respect to various fungi and bacteria. Twelve novel triorganotin(IV) complexes have been synthesized by reacting 4-Aminophenol with R3SnCl in (1:1) L/M molar ratio. In the first step ligand was being reacted with R3SnCl in anhydrous...
